Abstract
The invention discloses a method for obtaining illumination intensity suitable for growth and development of juvenile pomfret and relates to the pampus artificial breeding technology. A juvenile pomfret breeding unit and daily management are adopted. The juvenile pomfret breeding unit comprises a water cylinder with the diameter of 1.5 m and water depth of 1 m, water temperature is 15+/-3 DEG C, salinity is 28-30 %o, pH is 7.4-7.9, and dissolved oxygen is 5 mg/L or above. Daily management is conducted in the way that feeding is conducted twice a day, in the morning and afternoon, feeding amount is adjusted according to the amount of left feed, left feed is collected and dried, the feed intake of juvenile pomfret is calculated, and one third of water is changed each day. The method is characterized in that a fluorescent lamp is hung above the center of the water cylinder, illumination intensity is 500 lx, illumination intensity is guaranteed by adjusting the height of a lamp tube of the fluorescent lamp, photoperiod is set to be 12L: 12D, and that means illumination time in a day is 12 h. By adopting the illumination intensity of 500 lx, growth and sexual maturity of juvenile pomfret can be promoted.
Description
Technical field
The present invention relates to seawater fish large-scale cultivation technology, especially Pampus artificial culture technology.
Background technology
Intensity of illumination is the key factor that affects healthy fish growth. Illumination meeting is moved about, is ingested fishPhysiological status, Nutrition and Metabolism exert an influence. Suitable intensity of illumination can promote fish, reduces baitMaterial loss, promotes fish growth. Illumination meeting reduction fish a little less than crossing are discovered bait, easily cause baitMaterial waste, and affect fish growth. Cross strong illumination and can produce pressure to fish, cause fish notPeace, causes food ration to reduce, thereby reduces fish growth speed. Suitable illumination can also promote fishThe sexal maturity of class, thus the fertility of fish improved. Intensity of illumination is to fish reproduction, Nutrition and MetabolismInfluence degree there are differences because of the difference of fish, and same fish are in the different stages of developmentRequired intensity of illumination is also different. So can increase the feed intake of fish by regulation and control intensity of illumination,Promote that fish body is healthy and grow.
The research of the impact that at present, existing a large amount of relevant intensity of illumination is grown on seawater fish andReport, but there is not yet the report aspect silvery pomfret cultivation. For silvery pomfret is set up a kind of suitable illuminationIntensity, has great importance for improving and enriching silvery pomfret artificial culture technology.
Summary of the invention
The object of the invention is to propose a kind of foundation and be applicable to intensity of illumination that pomfret parr growsMethod, can improve the growth performance of pomfret parr, and promotes the growth of sexual gland.
Technical scheme of the present invention adopts pomfret parr cultivation unit and daily management, pomfret parr cultivationUnit comprises that being equipped with diameter is 1.5m, the bucket that the depth of water is 1m, and 15 ± 3 DEG C of water temperatures, salinity 28-30 ‰,PH7.4-7.9, more than dissolved oxygen remains on 5mg/L, daily management be the morning and afternoon at twiceCarry out feeding, adjust feeding amount according to surplus material amount, collect surplus material, and dry, estimation pomfret parrFeed intake, changes water 1/3rd every day, it is characterized in that at fluorescence of bucket center overhungLamp, intensity of illumination 500lx, ensures intensity of illumination, periodicity of illumination by the height that regulates fluorescent lamp tubeBe set as: 12L:12D, in one day, light application time is 12h.
Outstanding feature of the present invention is to set up the method that is applicable to the pomfret parr intensity of illumination of growing,Fill up pomfret parr and grown and be applicable to the blank of intensity of illumination, under the intensity of illumination of 500lx,Growth performance, the sexual gland index of pomfret parr have had significant raising.
Detailed description of the invention
The specific embodiment of the present invention adopts pomfret parr cultivation unit and daily management, silvery pomfret childrenFish culture unit comprises that being equipped with diameter is 1.5m, the bucket that the depth of water is 1m, 15 ± 3 DEG C of water temperatures, saltDegree 28-30 ‰, pH7.4-7.9, more than dissolved oxygen remains on 5mg/L, daily management be in the morning andCarry out at twice feeding afternoon, adjust feeding amount according to surplus material amount, collect surplus material, and dry, estimationThe feed intake of pomfret parr, changes water 1/3rd every day, glimmering one of bucket center overhungLight modulation, intensity of illumination 500lx, ensures intensity of illumination, illumination week by the height that regulates fluorescent lamp tubePhase is set as: 12L:12D, in one day, light application time is 12h.
This method is by its technique effect of following experimental verification: select 9 buckets (diameter is 1.5m,The depth of water is 1m), 15 ± 3 DEG C of water temperatures, salinity 28-30 ‰, pH7.4-7.9, dissolved oxygen remains on 5mg/LAbove, at fluorescent lamp of each bucket center overhung, each bucket is moulded with 2 layers of blackMaterial cloth shade; 9 buckets are divided into 3 groups, and 3 is one group, first group of fluorescent lamp intensity of illumination 300Lx, second group of fluorescent lamp intensity of illumination 500lx, the 3rd group of fluorescent lamp intensity of illumination 700lx, Mei GeshuiBucket is put 12 tail pomfret parrs, and average weight is 66.38 ± 2.38g, and intensity of illumination is with water surface centerMeasured value be as the criterion, regulate the height of fluorescent tube to ensure the intensity of illumination of each bucket, intensity of illumination is usedTES-1334A digital display illumination photometer is measured, and with the lamplight timer regulating illumination cycle, (periodicity of illumination is setFor: 12L:12D, in one day, light application time is 12h); Experiment schedules to last 60d, and experimental session respectivelyIn the morning (08:30-09:30) and afternoon (14:00-15:00), carry out at twice feeding, feed every dayTotally 2 hours food time, adjust feeding amount according to surplus material amount, collect surplus material, and dry, estimation silvery pomfretThe feed intake of juvenile fish; Change water 1/3rd every day; Respectively 30,60d sampling, each bucket gets 3Tail fish, weighs in, and collects sexual gland, and weighs.
Table 1: recorded intensity of illumination to pomfret parr end weight, weightening finish, specific growth rate, material anharmonic ratio,The impact of survival rate and sexual gland index.
Note: with the expression significant difference (p < 0.05) in data in a line with different letters.
Weightening finish=end weight-first starting weight
Specific growth rate=100 × (just starting weight of ln end weight-ln)/experiment number of days
Material anharmonic ratio=feed intake/weightening finish
Survival rate=(experiment fish sum-death toll)/experiment fish sum × 100%
Sexual gland index=sexual gland weight/body weight
As can be seen from Table 1, experiment 30 days and 60 days, intensity of illumination was 500lx group experiment fishWeightening finish, specific growth rate, material anharmonic ratio be all better than other groups, illustrate and use the intensity of illumination of 500lxCan promote growing of pomfret parr; Analyze the sexual gland index of silvery pomfret and find, 500lx and 700lxBetween experimental group, without significant difference, and two groups be all significantly better than 300lx experimental group, illustrates and keep enoughIntensity of illumination can promote the sexal maturity of silvery pomfret; From saving the angle of the energy, recommendation 500lx'sIntensity of illumination. The discovery of comprehensive analysis experimental result, 500lx is best suited for the light that pomfret parr growsAccording to intensity.
